Title: Phase grating
Inventor: YONEYAMA MASAYUKI
IPC: H04N5/357
Filed: 1991-07-24
Abstract: PURPOSE:To remove a false signal due to the phase grating and to improve the degree of freedom of optical design by arranging the phase grating at a distance which is an integral multiple of a distance where the video signal obtained from an image pickup element has no unnecessary beat signal. CONSTITUTION:In an image pickup device which uses the phase grating 2 as an optical low-pass filter, the grating pitch B of the phase grating 2 is set to an integral multiple of the picture element pitch A of the image pickup element 3 and the phase grating 2 is arranged at the distance which is an integral multiple of the distance where the video signal obtained from the image pickup element 3 has no unnecessary beat signal when the pitch B of the phase grating is equal to the picture element pitch of the image pickup element 3. While the phase grating 2 is used, the limitations of the phase grating arrangement are removed, the false signal due to the use of the phase grating is removed, and the manufacture of the phase grating is facilitated. Therefore, the beat signal generated by the phase grating 2 is removed and the conditions of an image pickup lens which is applicable with the phase grating 2 are relaxed to constitute the image pickup device of high picture quality which uses the phase grating 2.

The outer face of this coating film is subjected to aging treatment in a specified manner. The coating film is then dipped in the soln. of phosphonates such as C 8 F 17 SO 2 (CH 2 CH 3 )C 2 H 4 PO(OH) 2  or CF 3 (CF 2 ) 11 (CH 2 ) 3 PO (OH) 2  having at least six fluorinated carbon atoms and their salts. The coating film can be treated with a chromate soln., if necessary, before the phosphate treatment.

Title: Power failure processing system
Inventor: UNNO NOBUO
IPC: G06F1/00
Filed: 1985-08-22
Abstract: PURPOSE:To prevent a system from malfunction by insulating an input AC power supply from a voltage drop detecting output through a photocoupler, and when voltage drop is continued for a fixed period, disconnecting a power supply ready signal. CONSTITUTION:The system is constituted of a power failure detecting circuit 1, a counter 2, a flip flop (FF)3 and a gate circuit 4. The circuit 1 detects an input AC power supply by the voltage drop of a full-wave rectified DC voltage and the input AC power supply is insulated from a voltage drop detecting output. The counter 2 counts up clocks from the detection of power failure, and after a fixed period, outputs a count-over signal to invert the FF3. The counter 2 can optionally select the setting of a preset value and can be accurately driven for said fixed period. Consequently, the gate circuit 4 outputs a ready signal RDY2 to be disconnected at the detection of power failure on the basis of a ready signal RDY1 outputted from a power supply control part and an output signal from the FF3.

Filed: 1989-07-20
Abstract: PURPOSE:To prevent the occurrence of offset when a color image is copied on double-sides and to improve color image quality by controlling the temperature of a roller which comes into contact with a front surface higher than that of a roller which comes into contact with the back surface when a transfer material which has a fixed picture on its front surface and a unfixed picture on the back surface is fixed. CONSTITUTION:The fixing roller 29 and the pressure roller 30 are provided with heaters 36 and 37, respectively. When the front surface is fixed, it is heated by both heaters 36 and 37 so that multi-layer color toner is sufficiently fixed. When the back surface is fixed, the temperature of the heater 37 on the side of the pressure roller 30 which comes into contact with the surface having the already fixed picture is lowered so that the fixed surface image is not overheated. Thereby, when the color image is copied on both-sides, the occurrence of the offset is prevented and the color image quality is improved.

Abstract: PURPOSE:To keep the contacting state between a magnetic recording head and a recording medium well with a light load applied by adjusting the contacting state of the head to the medium in accordance with the detection signal of a magnetic flux state detecting coil provided in a magnetic flux return path. CONSTITUTION:Detecting coils 8a and 8b having the same number of turns are wound around side leg parts 4c above and below a main magnetic pole 2 in the medium running direction. Respective modulation values based on detecting coils 8a and 8b are compared with each other by a differential amplifying circuit 15a, and the output signal from the differential amplifying circuit 15a is used to drive the first servo motor 10, and it is so driven that modulation values based no detecting coils 8 and 8b are equal to each other. If a magnetic recording head 1 is inclined relatively to a recording medium, there is a difference between detection signals of detecting coils 8a and 8b, and the first servo motor 10 is so driven that the difference is eliminated, and a head supporting base 9 is turned and displaced. Thus, the attitude of the magnetic recording head 1 is controlled, and the contacting state between them is always kept well.

Filed: 1997-07-11
Abstract: PROBLEM TO BE SOLVED: To provide a support mechanism for balancing a microscope, such that movement of the head of a doctor around the microscope is seldom limited. SOLUTION: This support mechanism for balancing a microscope is so designed that the tilt shaft 37 of a support link 38 supporting a microscope 15 is located below an immobile point F during the vertical shaking of each end 35a of a transverse link 35, so that the center G1 , of gravity between the microscope 15 and the support link 38 is balanced with the center G2 of gravity between the transverse link 35 and a vertical link 36 in the direction opposite to the vertical link 36 across a vertical shaft Z. In this case, since the microscope 15 is supported via the support link 38 journalled to the lower end 36a of the vertical link 36, the vertical link 36 does not exist around the microscope 15, and therefore sufficient ambient space can be secured.
